Abstract: Ferrite particles have, as a main component, a material represented by a composition formula MxFe3?xO4 (where M is at least one type of metal selected from a group made of Mg, Mn, Ca, Ti, Cu, Zn, Sr and Ni, 0<x<1), where the maximum height Rz of the particles falls within a range of 1.40 ?m to 1.90 ?m, and the degree of distortion Rsk of the particles falls within a range of ?0.25 to ?0.07. In this way, when the ferrite particles are used as the carrier of an electrophotographic image forming apparatus, even if an image formation speed is increased, the occurrence of a failure is reduced for a long period of time.

Abstract: By outside seawater flowing through a passageway into a water tank having a prescribed volume and installed in the sea with top above the surface of the water, power is generated by a generator provided in the passageway. Therefore, by means of the simple configuration of installing the water tank in water, it is possible to store a prescribed amount of electric power depending on the volume of the water tank and loss is low because the length of the passageway for guiding the seawater into the generator is extremely short compared with conventional systems, making it possible to supply as necessary stable electric power from hydroelectric power generation with good power generation efficiency.

Abstract: A In a noise suppression apparatus, an extractor extracts a noise component from an audio signal. A stationary noise estimator estimates stationary noise included in the noise component. A first noise suppressor removes a spectrum of the stationary noise from a spectrum of the audio signal to an extent determined by a subtraction factor. A non-stationary noise estimator estimates a spectrum of non-stationary noise by subtracting the spectrum of the stationary noise from the spectrum of the noise component. A factor setter generates a filtering factor for emphasizing a target sound component contained in the audio signal from the spectrum of the non-stationary noise. A second noise suppressor performs a filtering process using the filtering factor on the audio signal after processing of the first noise suppressor.

Abstract: A resonance element array 200 is disposed between a primary radiator 1 and a lens 3. In the resonance element array 200, resonance elements of linear conductors and variable reactance circuits are arranged on a dielectric substrate. A control voltage is applied to a fixed variable reactance circuit by a control portion so that a fixed resonance element is excited by an electromagnetic wave from the primary radiator 1 and the direction of optical path to be collimated by the lens 3 is electronically changed. Thus, an antenna device, in which a beam scanning is speeded, power consumption for the beam scanning is reduced, operation noise in the beam scanning is eliminated, the reliability is increased, and, when required, the beam direction can be directed to any direction, can be obtained. Furthermore, when necessary, the beam radiation pattern can be changed.
